GitHub Actions Branch Drift Audit

核心功能：读取GitHub Actions运行JSON，按仓库、工作流、分支分组，对比基线分支的失败率、平均运行时漂移，标记警告/严重等级，支持CI失败门限。典型场景：在CI流程中提前发现分支CI可靠性回归，避免问题流入主线。输入为可选配置参数，输出支持文本或JSON格式，可用于流水线检查与分类面板。

GitHub Actions Branch Drift Audit

Use this skill to catch branch-specific CI reliability regressions before they spread into your mainline release flow.

What this skill does

  • Reads GitHub Actions run JSON exports
  • Groups runs by repository + workflow + branch
  • Selects a baseline branch per repository/workflow (defaults to main|master)
  • Compares each non-baseline branch against that baseline on:
    • failure-rate drift (percentage points)
    • average runtime drift (ratio)
  • Flags warning/critical drift severity and supports CI fail gates
  • Emits text or JSON output for pipeline checks and triage dashboards

Inputs

Optional:

  • RUN_GLOB (default: artifacts/github-actions/*.json)
  • TOP_N (default: 20)
  • OUTPUT_FORMAT (text or json, default: text)
  • MIN_RUNS_PER_BRANCH (default: 2)
  • MIN_BRANCHES (default: 2)
  • BASELINE_BRANCH_MATCH (default: ^(main|master)$)
  • WORKFLOW_MATCH (regex, optional)
  • WORKFLOW_EXCLUDE (regex, optional)
  • REPO_MATCH (regex, optional)
  • REPO_EXCLUDE (regex, optional)
  • FAILURE_DRIFT_WARN_PP (default: 10)
  • FAILURE_DRIFT_CRITICAL_PP (default: 25)
  • RUNTIME_DRIFT_WARN_RATIO (default: 1.25)
  • RUNTIME_DRIFT_CRITICAL_RATIO (default: 1.6)
  • FAIL_ON_CRITICAL (0 or 1, default: 0)

Collect run JSON

gh run view <run-id> --json databaseId,workflowName,event,conclusion,headBranch,headSha,createdAt,updatedAt,startedAt,url,repository \
  > artifacts/github-actions/run-<run-id>.json

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
BASELINE_BRANCH_MATCH='^(main|release/.*)$' \
MIN_RUNS_PER_BRANCH=3 \
bash skills/github-actions-branch-drift-audit/scripts/branch-drift-audit.sh

JSON output with fail gate:

RUN_GLOB='artifacts/github-actions/*.json' \
OUTPUT_FORMAT=json \
FAIL_ON_CRITICAL=1 \
bash skills/github-actions-branch-drift-audit/scripts/branch-drift-audit.sh

Run with bundled fixtures:

RUN_GLOB='skills/github-actions-branch-drift-audit/fixtures/*.json' \
bash skills/github-actions-branch-drift-audit/scripts/branch-drift-audit.sh

Output contract

  • Exit 0 in report mode (default)
  • Exit 1 when FAIL_ON_CRITICAL=1 and one or more drift rows are critical
  • Text mode prints summary + ranked branch drift rows
  • JSON mode prints summary + drift rows + critical-only slice
